Normal ceiling fan is 80W

You can buy dc fan at 30W.

100 hour is 8 unit vs 3 unit
1 unit is around 22 sen/per unit
1 day 12 hour
RM7.02 vs RM2.64
1 month differential is just around RM4.38
u buy a rm200 fan vs rm 400 fan, u need 50 month to save back the differential

Please calculate for me. I'm using Panasonic DC fan for the past 2 years.

My living area fan is switched on 24x7 because I have a dog in the house.

How much I saved?

30W x 24 x 365 = 262.8KW/year  = RM57.64 x 2 = RM115.28
80w x 24 x 365 = 700kw/year = RM154 x 2 = RM308
RM308-115.28 = 192.72

now
normal fan you buy RM200(consider higher class model)
inverter fan you buy RM459

fan differential RM459-RM200 = RM259
RM259-192.72 = RM66.28

u still need 7x24x1 year to start SAVING!
i hope ur fan still havent breakdown next year
